“…Figure 5 (a) shows that the tubular structure of MWCNTs and it can be observed that MWCNTs has inter-planar spacing of 0.34 nm as reported by others 27 . TEM images in Figure 5 (b) showed that the SiCNTs has rough surface which may due to the reaction of SiO gas with carbon atoms at the surface of MWCNTs, resulted in the formation of defects as some of carbon atoms formed CO gas as explained later.…”

Silicon carbide nanotube (SiCNTs) has been proven as a suitable material for wide applications in high power, elevated temperature and harsh environment. For the first time, we reported in this article an effective synthesis of SiCNTs by microwave heating of SiO 2 and MWCNTs in molar ratio of 1:1, 1:3, 1:5 and 1:7. Blend of SiO 2 and MWCNTs in the molar ratio of 1:3 was proven to be the most suitable for the high yield synthesis of β-SiCNTs as confirmed by X-ray diffraction pattern. Only SiCNTs were observed from the blend of MWCNTs and SiO 2 in the molar ratio of 1:3 from field emission scanning electron microscopy imaging. High magnification transmission electron microscopy showed that tubular structure of MWCNT was preserved with the inter-planar spacing of 0.25 nm. Absorption bands of Si-C bond were detected at 803 cm -1 in Fourier transform infrared spectrum. Thermal gravimetric analysis revealed that SiCNTs from ratio of 1:3 showed the lowest weight loss. Thus, our synthetic process indicates high yield conversion of SiO 2 and MWCNTs to SiCNTs was achieved for blend of SiO 2 and MWCNTs in molar ratio of 1:3.

“…Most GPs are below 10 nm in the agglomerate; the dark areas have a stack of GPs, while lighter areas indicate the presence of thinner stacked lamellae. In addition, it is noteworthy that the electron diffraction analysis of the CNPs, results in a characteristic interplanar distance of 3.5Å between graphene layers [50,51]. Figure 5(e) shows plasma treated GPs, where clusters (in red circles) might suggest the evidence of PP grafted on its surface.…”

Carbon nanofibers (CNFs), graphene platelets (GPs), and their mixtures were treated by plasma polymerization of propylene. The carbon nanoparticles (CNPs) were previously sonicated in order to deagglomerate and increase the surface area. Untreated and plasma treated CNPs were analyzed by dynamic light scattering (DLS), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, and thermogravimetric analysis (TGA). DLS analysis showed a significant reduction of average particle size, due to the sonication pretreatment. Plasma polymerized propylene was deposited on the CNPs surface; the total amount of polymerized propylene was from 4.68 to 6.58 wt-%. Raman spectroscopy indicates an increase in the sp 3 hybridization of the treated samples, which suggest that the polymerized propylene is grafted onto the CNPs.

“…25 Synthesized SWCNT lengths vary from the millimeter 26 to sub-100 nm (though individual SWCNTs on the centimeter scale have been reported 27 ), dependent on synthesis route; however, they are most commonly around 1− 2 μm. Multiple nanotubes may be nested coaxially to form (usually larger) MWCNTs 28 with typical intertube distances of 3.2−3.5 Å.…”

Since the discovery of buckminsterfullerene over 30 years ago, sp 2 -hybridised carbon nanomaterials (including fullerenes, carbon nanotubes, and graphene) have stimulated new science and technology across a huge range of fields. Despite the impressive intrinsic properties, challenges in processing and chemical modification continue to hinder applications. Charged carbon nanomaterials (CCNs), formed via the reduction or oxidation of these carbon nanomaterials, facilitate dissolution, purification, separation, chemical modification, and assembly. This approach provides a compelling alternative to traditional damaging and restrictive liquid phase exfoliation routes. The broad chemistry of CCNs not only provides a versatile and potent means to modify the properties of the parent nanomaterial but also raises interesting scientific issues. This review focuses on the fundamental structural forms: buckminsterfullerene, single-walled carbon nanotubes, and single-layer graphene, describing the generation of their respective charged nanocarbon species, their interactions with solvents, chemical reactivity, specific (opto)electronic properties, and emerging applications.
